Flight testing is being conducted at NASA's Armstrong Flight Research Center in Edwards, CA, to determine whether flexible trailing-edge wing flaps are a viable approach to improve aerodynamic efficiency and reduce noise generated during takeoffs and landings.
Toho Tenax has developed a new prepreg that offers super-high-heat and -oxidation resistance suited to aircraft and automotive engine compartments. The supplier also recently released a new rapid-curing prepeg for increased productivity.
Oxford Performance Materials launched in December the first two grades of its OXFAB 3-D printing technology—OXFAB-N and OXFAB-ESD—suitable for aerospace and other industrial markets, including transportation, energy, and semiconductor applications. The company claims this is the first time PEKK is being used for 3-D printing in aerospace and industrial applications.
Treating molten metal with ultrasound is cleaner and more efficient than using argon rotary degassing to produce high-quality castings, according to scientists at Brunel University London. Cost reduction is another benefit, demonstrated in the research team's pilot-scale trials.
3-D laser scanning from NVision helped a certified FAA repair station document its work on a passenger jet part with such precision that the station was able to obtain the necessary FAA approval for the repair in much less time than is usually required.
With air traffic expected to increase four-fold between now and 2050, a global fleet of composite planes could help reduce carbon emissions by up to 15%, a value researchers say roughly corresponds to current emissions levels.
